Supporting data for Design, characterisation, and optimisation of lattice metamaterials: Application in lightweight structures Chermila Piyumi Kandamulla Waduge (9391871) Structural engineering Topology Optimisation tensile testing data Compression test results numerical homogenization <p dir="ltr">This thesis addresses this gap by developing invariant-unit-cell homogenised models of conventional and re-entrant honeycomb lattices and by demonstrating their applicability in two distinct applications: (i) topology-optimised auxetic honeycomb sandwich beams, and (ii) a near-zero Poisson's ratio (NZPR) lumbar interbody fusion (LIF) implant, validated at the whole-implant scale. The dataset includes experimental data, images, and Python, MATLAB and UMAT codes used in this study.</p> 2026-09-23T05:47:37Z Dataset Dataset 10.25442/hku.33416938.v1 https://figshare.com/articles/dataset/Supporting_data_for_Design_characterisation_and_optimisation_of_lattice_metamaterials_Application_in_lightweight_structures/33416938 CC BY-NC 4.0 Open Access after 2028-09-02
